The Lowdown
Alright folks, Rusty here. I'm not gonna sugarcoat it. The next couple of weeks for Kennebunk Beach look bleak for surf. The ocean is basically flat and disorganized. We got a long stretch of poor conditions ahead, with just a couple of tiny windows where it might be worth a paddle. But don't get your hopes up for anything epic.
Water temp is around 66°F, which is about normal for the season. The main problem is the total lack of swell. The wave energy is weak, mostly in the 50s and 60s to start, which is just a whisper. Swell direction is all over the place, but mostly from the east-southeast, which isn't doing us any favors.
Friday the 21st is a complete no-go. There's a tiny 2ft swell with a short 8-second period and weak energy at 58. It's clean with a light offshore breeze, but there's nothing to surf. Saturday the 22nd is equally poor. A bit of rain and the swell drops to 2ft in the morning. The afternoon does see a bump to 3ft, but the period drops to a terrible 6 seconds and the energy is weak. Just a mushy, crumbly mess.
Sunday the 23rd and Monday the 24th are poor as well. Small surf with cross-shore and onshore winds. Monday afternoon sees a period jump to 11 seconds, but the swell height is only 1ft. The energy is moderate at 144, but without any size, it's just a lot of moving water with no face.
Tuesday through Thursday is a dead zone. Swell heights are tiny, from 0.6ft to 2ft, and the winds are onshore or cross-shore. It's choppy, messy, and completely frustrating.
But, there's a little light at the end of the tunnel. Friday, August 28th. The morning is glassy with a 2ft swell, and then the afternoon goes perfectly calm and glassy. The swell nudges up to 2ft with a 10-second period and the energy is a moderate 102. It's still small, but it's the cleanest we'll see all week. This is your chance to get on the log and just enjoy being out there, even if the waves are small.
Saturday the 29th holds a bit of that promise. The morning has a light offshore breeze and a 3ft swell. It's clean, but the period drops back to 8 seconds. Still poor quality but consistent enough to maybe snag a few fun ones. This is the other standout, but it's still small stuff.
After that, we're back to the doldrums. From the end of August into the first week of September, the swell stays weak and the winds are scattered. A possible thunderstorm on Tuesday, September 1st with strong winds will make it a complete mess.
The last possible event is on Thursday, September 3rd, which is more than a week away. The morning is clean with a light offshore breeze and a 1ft swell, but the afternoon brings a slightly bigger 4ft swell from the south, but with a crumbly 5-second period. It's a long way out, so take it with a grain of salt. It's promising, but not something to plan your life around.
So, bottom line: this isn't a surf week. It's a beach week. The only real windows are Friday the 28th and maybe Saturday the 29th, but even then, you're just getting wet. With low energy like this, it shouldn't stay poor for too long, forecasts can change. If the wind really pipes up and the surf is that junky, it might be better for the kite surfers than the paddle surfers.
Stay patient. Rusty out.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
